A highly selective Mn(I)-catalyzed dienylation of arenes and heteroarenes with acetylated allenes is described. The reported transformation proceeds by a simple one-pot procedure and delivers linear 1,3-dienes as single products with high stereoselectivity and total regioselectivity. A great variety of allenic substrates bearing diverse substitution patterns can be applied in this protocol where the
